Introduction

1.5 Batteries

This monitor is designed to operate run battery power when during transport or whenever the
power supply is interrupted. The battery is charged automatically when the monitor is
connected to AC power, no matter the monitor is powered on or not.

The battery symbol displayed on the main screen tells the status of the battery.





Besides, the battery indicator also indicates the status of the battery.

 ON: The battery is being charged or the battery is fully charged.

 OFF: No battery is inst alled. If the battery is installed but the monitor is not

The battery is installed in the battery slot. The solid part indicates its capacity.

No battery is installed in the battery slot.

connected to AC power and not turned on, the indicator will also be off.

 Flashes: The monitor is powered by the internal battery.

The capacity of the internal battery is limited. When the battery capacity is too low, a high
level alarm is triggered and the “Battery two low” message is given in the technical alarms
area. At this moment, the AC power shall be applied to the monitor.

Note

Remove the battery before transport, or if the monitor is not likely to be used for an
extended period of time.

Warning

Keep the battery out of the reach of children.
Use only the battery specified by the manufacturer.

1.5.1 Battery Maintenance

Conditioning a Battery

A battery should be conditioned before it is used for the first time. A battery conditioning cycle
is one uninterrupted charge of the battery, followed by an uninterrupted discharge of the

1-13

Introduction

battery. Batteries should be conditioned regularly to maintain their useful life. Condition a
battery once when it is used or stored for two months, or when its run time becomes
noticeably shorter.

To condition a battery, follow this procedure:

1. Disconnect the monitor from the patient and stop all monitoring or measuring.

2. Insert the battery in need of conditioning in the battery slot of the monitor, and leave the

other slot empty if your minitor has two slots.

3. Apply AC power to the monitor and allow the battery to charge uninterrupted for 10 hours.

4. Remove AC power and allow the monitor to run from the battery until it shuts off.

5. Apply AC power again to the monitor and allow the battery to charge uninterrupted for 10

hours.

6. This battery is now conditioned and the monitor can be returned to service.

Checking a Battery

The performance of a rechargeable battery may deteriorate over time. To check the
performance of a battery, follow this procedure:

1. Disconnect the monitor from the patient and stop all monitoring or measuring.

2. Apply AC power to the monitor and allow the battery to charge uninterrupted for 10 hours.

3. Remove AC power and allow the monitor to run from the battery until it shuts off.

4. The operating time of battery reflects its performance directly.

If your monitor has two battery slots, you can check two batteries at the same time. Please
replace the battery or contact with the maintenance personnel if its operating time is
significantly lower than the specified time.

Note

Life expectancy of a battery depends on how frequent and how long it is used. For a
properly maintained and stored lead-acid or lithium ion battery, its life expectancy is
about 2 or 3 years respectively. For more aggressive use models, life expectancy can
be less. We recommend replacing lead acid batteries every 2 years and lithium ion
batteries every 3 years.
The battery might be damaged or malfunctioned if its operating time is too short after
being fully charged. The operating time depends on the configuration and operation.
For example, measuring NIBP more frequently will also shorten the operating time.

1-14

Introduction

1.5.2 Battery Recycling

When a battery has visual signs of damage, or no longer holds a charge, it should be
replaced. Remove the old battery from the monitor and recycle it properly. To dispose of the
batteries, follow local laws for proper disposal.

Warning

Do not disassemble batteries, or dispose of them in fire, or cause them to short circuit.
They may ignite, explode, leak or heat up, causing personal injury.

Chapter 5 Alarm

This chapter gives general information about the alarm and corresponding remedies.

Alarm setup and prompt messages are provided in respective parameter setup sections.

Warning

When PM-8000 is powered on, the system may verify the audio and visual alarm
function.

Upon turning on the monitor, a “Dang” will be heard and at the same time the indicator
will flash twice in yellow and red. This is used to verify the audio and visual alarm
function of the system. Therefore, the user should be carefully observe the status. If
the audio and visual alarm function is not normal, it indicates that the monitor cannot
be used to monitor a patient. Please contact Mindray Company or service center.

5.1 Alarm Modes

5.1.1 Alarm Level

Each alarm, either technical or physiological, has its own level. For alarm of higher level,
when it occurs, the system will give prompt in a more alert way. Some alarm’s level can be set
by the user via software. Others can not be changed once defined by the system. Alarms in
PM-8000 are divided into three levels, that is, high, medium and low.

High-level alarm indicates the patient’s life is in danger or the monitor under using has serious
problem in technical respect. It is the most serious alarm.
Medium-level alarm means serious warning.
Low-level alarm is a general warning.

Alarms are classified into three categories, which are physiological alarm, technical alarm and
general alarm. Physiological alarm refer to those alarms triggered by patient’s physiological
situation which could be considered dangerous to his or her life, such as heart rate (HR)
exceeding alarm limit (parameter alarms). Technical alarm refer to system failure which can
make certain monitoring process technically impossible or make monitoring result
unbelievable. Technical alarm is also called System Error Message. General alarm belongs to
those situations that can not be categorized into these two cases but still need to pay some
attention.

5-1

Alarm

PM-8000 has preset the alarm level for the parameters. You can also modify the alarm level
using the method described in this chapter.

Alarm level of the System Error Message (technical alarm) is pre-set in the system.
All technical alarm level and general alarm level, some of the physiological alarm level are
pre-set in the system and can not be changed by user.

5.1.2 Alarm Modes

When alarm occurs, PM-8000 may raise the user’s attention in at least three ways, which are
audio prompt, visual prompt and description. Audio and visual prompt is given by TFT display
device, the speaker on the display device and the alarm indicator. Description is displayed on
the screen. Physiological alarm is displayed in the Physiological Alarm area. Most of technical
alarms are displayed in the Technical Alarm area. Technical alarms related to NIBP
measurement are displayed in the NIBP Technical Alarm area at the bottom of NIBP
parameter area.

Note

The Physiological Alarm area is on the upper right part of the screen. The Technical
Alarm area is to the left side of the Physiological Alarm area.

Note

The concrete presentation of each alarm prompt is related to the alarm level.

Alarm prompt of the parameter exceeding the alarm limit.
When physiological alarm of the monitored parameter exceeds the alarm limit, besides using
the above-mentioned three ways to give the alarm prompt, the monitor also gives alarm by
making the monitored parameter flash in the frequency of 1Hz. If at this time the upper and
lower limits of the parameter are displayed, they will flash in the same frequency (1Hz).

Screen Display

When an alarm occurs, the parameter triggering the alarm flashes. “*” signal appears on the
screen indicating the occurrence of alarm. Red “***” indicates high-level alarm, yellow “**”
indicates medium-level alarm, and yellow “*” indicates low-l evel alarm. Technical alarm will not
prompts “*” signal.

Review & Record Frozen Waveforms



6.1 General

When monitoring a patient, you may freeze the waveforms of interest so as to view them
carefully. Generally you can review maximally 40 seconds of a frozen waveform. If required,
you may also use recorder to print out a frozen waveform. The Freeze function of this monitor
has following features:

 Freeze status can be activated on any operating screen;
 At the same time of entering the Freeze status, the system exits all other operating

menus. Besides, the system freezes all waveforms in the Waveform area of the Basic
Screen, or Full-lead ECG waveforms and the extra waveform (if available) on the
Full-lead ECG screen. Nevertheless the Parameter area refreshes normally.

 In the Freeze status, it does not affect the display and refresh of the Trend Graph

area on the trend screen, the display and refresh of oxyCRG on the Dynamic Refresh
screen, or the display and refresh of the Viewbed window on the Viewbed screen.

 The frozen waveforms can be reviewed or recorded.

6.2 Enter/Exit Freeze Status

Enter Freeze Status

In the Non-Freeze status, press the “FREEZE” button on the front panel of the monitor to let
the system exit the Menu being currently displayed (if available), then enter the Freeze status
and display the popup “FROZEN” menu. In the Freeze status, except Viewbed waveforms, all
other waveforms are frozen. In other words, the system will no longer refresh all other
waveforms.

Exit Freeze Status

In the Freeze status, executing any of the following operations will command the system to
exit the Freeze status:

 Select the “EXIT” option on the “FROZEN” menu;
 Press the “FREEZE” button on the front panel again;

6-1

Freeze

 Press the non-immediate-to-execute button (such as a button once pressed, a

menu will pop up for you to further select an option )on the front panel and system
buttons of MAIN and MENU;

 Execute any operation that may trigger the adjustment of the screen or display of

a new menu.

After exiting the Freeze status, the system will discharge the Freeze status, clear
screen waveforms and resume to display real-time waveforms. In the Screen Refresh
mode, the system begins scanning waveforms from the extreme left one. In the Screen
Scroll mode, the system begins displaying and scrolling waveforms from the extreme
right one.

6.3 FROZEN Menu

Press the “FREEZE” button on the button module, the FROZEN menu will appear on the
bottom part of the screen. At the same time, the system enters the Freeze st atus.

Figure 6-1 FROZEN menu

 WAVE 1： used to select the first frozen waveform to record. The

pull-down list of this item gives you the names of all frozen waveforms
displayed on the screen.

 WAVE 2： used to select the second frozen waveform to record. The

pull-down list of this item gives you the names of all waveforms displayed
on the screen.

 RECALL：used to review frozen waveforms.
 REC: after selected, the system begins recording the frozen waveforms

selected in“WAVE 1” and“WAVE 2”.

 EXIT： after pressed, the system closes the FROZEN menu and exits

the Freeze status。

Note

Pressing the “FREEZE” button repeatedly in short time period may result in
discontinuous waveforms on the screen.

6.4 Reviewing Frozen Waveform

6-2

Freeze

By moving the waveform, you may review a waveform of 40 seconds before the moment
when it is frozen. For a waveform less than 40 seconds, the remaining part is displayed as a
straight line. Use the rotary snob on the front panel to move the cursor to the “RECALL”
option on the FROZEN menu. Press the knob, the option displays “L-RIGHT”. By turning the
knob left or right, frozen waveforms on the screen will move left or right correspondingly.
There is an arrow indicating upward under the right side of the last waveform. There is also a
time scale beside the arrow. “0S” is used to mark the moment when waveforms are frozen.
With waveforms moving right, this time mark will in turn change into -1S, -2S, -3S… These
time marks are applied to all waveforms on the screen.

6.5 Recording Frozen Waveform

In the Freeze status, you may output displayed frozen waveforms via the recorder. Maximum
2 waveforms can be output at one time. On the FROZEN menu, the pull-down lists of both
“WAVE 1” and “WAVE 2” give you all names of frozen waveforms on the screen, from which
you may select two. Select the “REC” option on the FROZEN menu to output parameters
generated upon the freezing moment and the two selected frozen waveforms. If one of the
two selected waveforms is closed or not available, only parameters and the other waveform
are recorded. If these two selected waveforms are all closed or not available, only parameters
are recorded. As for the function of recording frozen waveforms, you can only record the
waveforms displayed upon the freezing moment. The recording time length is the same as the
length of the waveform displayed on the screen. For example, if the speed of a waveform is
relatively fast, then it needs shorter time to record it. When recording frozen waveforms, the
system is still in the Freeze status. After completion of recording, if required, you may select
once more the waveform to be output and select “REC” option again to record the whole
selected waveforms. If the recorder does not exist, selecting the “REC” option can only call
out the prompt “Recorder does not exist” in the STATUS bar. For more detailed information
about recording, please refer to the chapter of “Recording”.

Chapter 9 Drug Calculation and
Titration Table

PM-8000 Portable Patient Monitor provides Drug calculation and titration table display
functions for fifteen drugs and outputs the content of titration table on the recorder.

9.1 Drug Calculation

The drug calculations that can be performed by the system are AMINOPHYLLINE,
DOBUTAMINE, DOPAMINE, EPINEPHRINE, HEPARIN, ISUPREL, LIDOCAINE, NIPRIDE,
NITROGLYCERIN and PITOCIN. Besides DRUG A, DRUG B, DRUG C, DRUG D and DRUG
E are also provided to flexibly replace any of the drugs.

Select “DRUG CALC” in SYSTEM MENU, the following “DRUG CALC” display appears:

Figure 9-1 DRUG CALC

The following formulas are applied for dose calculation:
Concentrat = Amount / Volume
INF Rate =DOSE / Concentrat
Duration = Amount / Dose
Dose = Rate × Concentrat

Operating method:

In the Drug Calculation window, the operator should first select the name of the drug to be

calculated, and then confirm the patient weight. Afterwards, the operator should also enter
other known values.
Turn the knob to select the value of the item to be calculated. Turn the knob to change the
value. When it is the required value, press the knob to view the calculation result. Each item
has its calculation range. If the result exceeds the range, display “---.--”

Note

For the drug calculation, the prerequisite is that the operator must first of all enter the
patient weight and drug name. The system first gives a group of random initial values,
which cannot be used by the operator as the calculation reference. Instead, he should
enter a new group of values at the doctor’s instruction.

Note

Each drug has its fixed unit or unit series. Operator must select the proper unit at the
doctor’s instruction. If the result exceeds the system-defined range, it will display “---”.

Note

After entering a value, a conspicuous prompt will appear in the menu warning the
operator to confirm the correctness of the entered value. The correct value is the
guarantee for the reliability and safety of the calculated results.

Note

In neonate mode, Drip Rate and Drop Size items are disabled.

Note

For each entered value, the system will always give a dialog box asking for the user’s
confirmation. You must be careful when answering each box. The calculated result is
reliable only after the entered value is confirmed to be correct.

Select the drug name：

Turn the knob to pick the DRUG NAME item in DRUG CALC menu. The user may select the
drug name in the pull-down list, including

Patient weight:

After accessing the DRUG CALC window, the operator should enter the patient weight into
the first or the second item. The entered weight will be used as the independent data only for
the calculation of drug concentration.

Note

This drug calculation function acts only as a calculator. That means the patient weight
in Drug Calculation menu and the patient weight in Patient Information menu are
independent from each other. Therefore if the Weight in Drug Calculation changes, the
Weight in Patient Information does not change. In this way, we can say, the Drug
Calculation menu is independent from other menus in the system. Any change of it will
not affect other information about the patient being currently monitored.

Chapter 10 Patient Safety

The PM-8000 Portable Patient Monitor is designed to comply with the International National
Safety requirements for medical electrical equipment. This device has floating inputs and is
protected against the effects of defibrillation and electrosurgery. If the correct electrodes are
used and applied in accordance with the manufacturer instructions, the screen display will
recover within 10 seconds after defibrillation.

This symbol indicates that the instrument is IEC 60601-1 Type CF equipment. The unit
displaying this symbol contains an F-Type isolated (floating) patient applied part providing a
high degree of protection against shock, and is suitable for use during defibrillation.

Warning

Do not touch the patient, bed or instrument during defibrillation.

Environment

Follow the instructions below to ensure a completely safe electrical installation. The
environment where the PM-8000 Portable Patient Monitor will be used should be reasonably
free from vibration, dust, corrosive or explosive gases, extremes of temperature, humidity, and
so on. For a cabinet mounted installation, allow sufficient room at the front for operation and
sufficient room at the rear for servicing with the cabinet access door open.

The PM-8000 Portable Patient Monitor operates within specifications at ambient temperatures
between 0℃ and 40℃. Ambient temperatures that exceed these limits could affect the
accuracy of the instrument and cause damage to the modules and circuits. Allow at least 2
inches (5cms) clearance around the instrument for proper air circulation.

Power Source Requirements

Refer to chapter Production Specification.

Grounding the PM-8000 Portable Patient Monitor

To protect the patient and hospital personnel, the cabinet of the PM-8000 Portable Patient
Monitor must be grounded. Accordingly, the PM-8000 Portable Patient Monitor is equipped
with a detachable 3-wire cable which grounds the instrument to the power line ground
(protective earth) when plugged into an appropriate 3-wire receptacle. If a 3-wire receptacle is
not available, consult the hospital electrician. If completeness of the protective grounding wire
is in doubt, the equipment must be operated with internal power supply.

10-1

Patient Safety

Warning

Do not use a 3-wire to 2-wire adapter with this instrument.

Connect the grounding wire to the equipotential grounding terminal on the main system. If it is
not evident from the instrument specifications whether a particular instrument combination is
hazardous or not, for example due to summation of leakage currents, the user should consult
the manufacturers concerned or else an expert in the field, to ensure that the necessary
safety of all instruments concerned will not be impaired by the proposed combination.

Equipotential Grounding

When other equipments are used together with the monitor, a grounding cable should be
used to connect the equipotential grounding connectors of the monitor and of other
equipments. This helps to reduce the potential differences between different pieces of
equipment, and ensure the safety of the operator and patient.

Warning

If the protective grounding (protective earth) system is doubtful, the monitor must be
supplied by inner power only.

Condensation

Make sure that during operation, the instrument is free of condensation. Condensation can
form when equipment is moved from one building to another, thus being exposed to moisture
and differences in temperature.

Warning

Possible explosion hazard if used in the presence of flammable anesthetics.

Chapter 12 ECG/RESP Monitoring

12.1 What Is ECG Monitoring

Monitoring the ECG produces a continuous waveform of the patient's cardiac electric activity
to enable an accurate assessment of his current physiological state. Only proper connection
of the ECG cables can ensure satisfactory measurement. On the Normal Display, PM-8000
provides display of 2-channel ECG waveforms.

■ The patient cable consists of 2 parts

information of the ECG accessories);
The cable that connects to the monitor;
The lead set that connects to the patient.

■ Using a 5-lead set, the ECG can derive up to two waveforms from two different leads.

For requested lead, you may choose from the left side of ECG waveform.

■ The monitor displays the Heart Rate (HR), ST segment and Arrhythmia analysis.

■ All of the parameters above can be set as alarm parameters.

(Refer to Chapter Accessories for more detailed

Note

In the default settings of PM-8000, the ECG waveforms are the first two waveforms
from top in the Waveform Area.

12.2 Precautions during ECG Monitoring

Warning

Do not touch the patient, table nearby, or the equipment during defibrillation.

Warning

Use only the original PM-8000 ECG cable for monitoring.

Warning

When connecting the cables and electrodes, make sure no conductive part is in
contact with the ground. Verify that all ECG electrodes, including neutral electrodes,
are securely attached to the patient.

12-1

ECG/RESP Monitoring

Warning

When apply the ECG cable with no resistances to Mindray patient monitor or other
patient monitors which themselves with no current limit resistance, it can’t be applied
to defibrillation.

Note

Interference from a non-grounded instrument near the patient and ESU interference
can cause inaccuracy of the waveform.

12.3 Monitoring Procedure

12.3.1 Preparation

1. Prepare the patient's skin prior to placing the electrodes.

■ The skin is a poor conductor of electricity, therefore preparation of the patient's skin
is important to facilitate good electrode contact to skin.

■ Shave hair from sites, if necessary.

■ Wash sites thoroughly with soap and water. (Never use ether or pure alcohol,

because this increases skin impedance).

■ Rub the skin briskly to increase capillary blood flow in the tissues and remove skin
scurf and grease.

2. Attach clip or snap to electrodes prior to placement.

3. Put the electrodes on the patient. Before attaching, apply some conductive jelly on the
electrodes if the electrodes are not electrolyte self-supplied.

4. Connect the electrode lead to the patient's cable.

5. Make sure the monitor is ready with power supply.

Warning

Check everyday whether there is skin irritation resulted from the ECG electrodes. If so,
replace electrodes every 24 hours or change their sites.

Note

For protecting environment, the electrodes must be recycled or disposed of properly.

Warning

Verify lead fault detection prior to the start of monitoring phase. Unplug the ECG cable
from the socket, the screen will display the error message “ECG LEAD OFF” and the
audible alarm is activated.

Recommended ECG Lead Placement for Surgical Patients

Warning

When using Electrosurgery equipment, leads should be placed in a position in equal
distance from Electrosurgery electrotome and the grounding plate to avoid cautery.
Electrosurgery equipment wire and ECG cable must not be tangled up.

The placing of the ECG leads will depend on the type of surgery that is being performed. For
example, with open chest surgery the electrodes may be placed laterally on the chest or on
the back. In the operating room, artifacts can sometimes affect the ECG waveform due to the
use of ES (Electrosurgery) equipment. To help reduce this you can place the electrodes on
the right and left shoulders, the right and left sides near the stomach, and the chest lead on

12-4

ECG/RESP Monitoring

the left side at mid-chest. Avoid placing the electrodes on the upper arms, otherwise the ECG
waveform will be too small.

Warning

When using Electrosurgery equipment, never place an electrode near the grounding
plate of the Electrosurgery device, otherwise there will be a great deal of interference
with the ECG signal.

Note

If a ECG waveform is not accurate, while the electrodes are tightly attached, try to
change the lead.

Note

Interference from a non-grounded instrument near the patient and ESU interference
can cause inaccuracy of the waveform.

Normal QRS complex should be:

 T all and narrow with no notches.
 With tall R-wave completely above or below the baseline.
 With pacer spike no higher than R-wave height.
 With T-wave less than one-third of the R-wave height.
 With P-wave much smaller than the T-wave.

For getting 1 mv calibrated ECG wave, choose ECG CAL button in ECG SETUP menu. A
message "when CAL, can't monitor! " prompts on the screen.

12.4 ECG Screen Hot Keys

Figure 12-4 the hot key for ECG

① Leads of channel 1:

1） The selectable leads are I, II, III, aVR, aVL, aVF, V .
2） When the ECG is 5-lead, the selectable leads are: I, II, III, aVR, aVL, aVF, V; when
ECG is 3-lead, the selectable leads are: I, II, III.
3） Leads on the ECG wave must not have the same name. Otherwise, the system will
automatically change the ECG waveform name that has the same name as the waveform
being currently adjusted to another name.

② Waveform gain of channel 1: used to adjust the size of ECG waveforms

Select gain value for each channel from ×0.25,×0.5,×1,×2, and auto. Under "auto"
mode, the monitor chooses an appropriate level automatically. A 1mv scale displays on
each ECG channel's right side. The height of 1mV bar is directly proportional to the
waveform amplitude.

Note

When the input signals are too large, the peak of the waveform may be not able to be
displayed. In this case the user may manually change the setup method of ECG
waveform according to the actual waveform so as to avoid the occurrence of the
unfavorable phenomena.

③ Filter method: used for displaying clearer and more detailed waveform

There are three filter modes for selection. DIAGNOSTI, MONITOR and SURGERY
modes may reduce perturbance and interference from Electrosurgery equipment. The
filter method is the item applicable for both channels, which is always displayed at the
waveform place of the channel 1 ECG waveform.

12-6

ECG/RESP Monitoring

Note

Only in Diagnosis mode, the system can provide non-processed real signals. In
Monitor or Sugery mode, ECG waveforms may have distortion of different extent. In
either of the latter two modes, the system can only show the basic ECG and the results
of ST analysis may also be greatly affected. In Surgery mode, results of ARR analysis
may be somewhat affected. Therefore, it is suggested that in the environment having
relative small interference, you’d better monitor a patient in Diagnosis mode.

ECG/RESP Monitoring

• ALM HI: used to set up the upper limit of ECG alarm.

• ALM LO: used to set up the lower limit of ECG alarm.

ECG alarm is activated when the heart beat exceeds set ALM HI value or falls below
ALM LO value.

ECG alarm limits:

Max. ALM HI Min. ALM LO Step
HR ADU 300 15 1
HR PED 350 15 1
HR NEO 350 15 1

Note

Please set the alarm limits according to clinical condition of individual patient. The
upper limit shall not exceed 20 beat/min higher than the patient's heart rate.

■ HR FROM

ECG, SpO
source according to the quality of signal. By picking ECG, the monitor prompts HR and
activates HR beep. By picking SpO
BOTH mode displays HR and PR simultaneously, when this item is picked, PR parameter is
displayed to the right side of SpO
the priority, i.e., if HR is available, whose sound will be sent out, but if HR is not available,
then the sound will be for PR.

■ HR CHANNEL

"CH1" to count the heart rate by CH 1 waveform
"CH2" to count the heart rate by CH 2 waveform
"AUTO" the monitor selects a channel automatically

■ LEAD TYPE: used to select either 5 LEADS or 3 LEADS.

■ SWEEP

Available options for ECG SWEEP are 12.5, 25.0, and 50.0 mm/s.

■ ST ANALYSIS

Pick this item to access ST ANALYSIS menu, the detailed information about the menu is
to be discussed in the following section.

■ ARR ANALYSIS

Pick this item to access ARR ANALYSIS menu, the detailed information about the menu
is to be discussed in the following section.

ECG/RESP Monitoring

Figure 12-6 ECG SETUP menu

In the sub-menu, following functions are available:

 ECG DISPLAY: Select NORMAL DISPLAY to display 2 ECG waveforms for 5-lead (for

3-lead, only 1 ECG waveform is displayed.). Select MULTI-LEADS DISPLAY, the
waveform area on the screen displays 6 ECG waveforms. Select HALF-SCAN
MULTI-LEADS, there are 4 ECG waveforms are displayed on the screen.
Note: If 3 LEADS is selected in the ECG SETUP menu, only NORMAL DISPLAY can be
selected for ECG DISPLAY item in the sub-menu.

 BEAT VOL

The options are from “10” to “0”. “10” indicates the maximum volume while “1” the
minimum,”0” indicates OFF. If your machine does not have "Multilevel Volume" function,
only four options are available for volume, “3”, “2”, “1” and ”OFF”.

Note

PITCH TONE volume is controlled through adjusting the heart beat volume. However, if
SPO2 is selected as “HR FROM” in “ECG SETUP”, the PITCH TONE volume will
accordingly controlled through adjusting “PR SOUND” in “SPO2 SETUP” menu. Refer
to the chapter about SPO2 to know the detailed information about PITCH TONE. ( If
your machine does not have "PITCH TONE" function, you can jump over this
paragraph)

 PACE

|

"ON" detected signal will be marked by a "

" above the ECG waveform.

"OFF" for non-pacemaking patient.

Note

If monitoring a patient with the pacemaker, set “PACE” to On. If monitoring a patient
without pacemaker, set “PACE” to Off.
If “PACE” is on, the system will not perform some types of ARR analysis. For detailed
information, please refer to the section: ARR ALARM. In the table, the ARR type marked
by All types applies to the analysis in all situations, marked by Non-paced applies only
to the analysis in the situation when the patient does not use pacemaker.

ECG/RESP Monitoring

 CASCADE: switch for ECG cascade. CASCADE: wave of each channel is displayed in

two lines. This function effects only when NORMAL DISPLAY is selected for ECG
DISPLAY.

 ECG CAL: pick this item to start calibrating ECG. The method to end CAL: re-select the

CAL key in the menu or re-select the lead name on the screen.

 ADJUST WAVE POS: used to adjust the position of the waveform on the screen. Pick to

access ADJUST WAVE POS dialog box. The user may use CH NAME item to select the
channel to be adjusted, UP-DOWN to adjust the position of the selected channel on the
screen, BACK TO DEFAULT to let the wave go back to the default position on the
screen.

Figure 12-7 ADJUST WAVE POS menu

 DEFAULT: pick this item to access the ECG DEFAULT CONFIG dialog box, in which the

user may select whether the FACTORY DEFAULT CONFIG or the USER DEFAULT
CONFIG is to be used. After selecting any of the items and exiting the dialog box, the
system will pop up the dialog box asking for the user’s confirmation.

Warning

For pacemaker patient, the pacing impulse analysis function must be switched on,
otherwise, the pacing impulse may be counted as normal QRS complex, which results
in failure of “ECG LOST” error detection.

■ For monitor with ST segment & Arrhythmia analysis software, refer to ST Segment

Monitoring and Arrhythmia Analysis for details.

Note

When Pacer Switch is On, the Arrhythmia events related to PVCs will not be monitored.
At the same time, the ST analysis will not be performed either.
